Over low-medium heat, saute' mushroom, garlic, Kitchen Karma, and pepper in melted butter. When mushrooms are cooked through, whisk in flour and cook for a few minutes more, stirring constantly, to remove the raw flour taste. Add milk and bring the mixture to a simmer over medium heat; keep stirring. When the mixture is thick and bubbly, remove from heat and serve with New Bleu Chicken or over sauteed chicken breasts.
